FAQ
Q: Where and by whom can I have my bike in and assembled?
A: Basically, any good bike store should fit it for you when you pay to have it fitted (since they didn't buy the bike there). However, there are official social bike shops that offer this service as well. You can find them at the Federal Employment Agency:
Q: How does customer service/warranty work after the sale?
A: When you have a problem with your bike, please leave us a message on the platform where you bought your bike or contact us directly: varunebikes.service@gmail.com
We will get back to you within one business day. It is best to describe your problem in detail and send pictures or make a video showing your problem. We will report your problem/video to our technical team and give you a solution.
Q: Can I ride in the rain?
A: Yes, there is no problem riding in moderate or light rain. Please make sure that the bike is completely dry before your next ride, and make sure that the bike is completely dry before your next ride, otherwise the bike will randomly disconnect. However, do not park your bike in the rain or wade through water. Soaking the vehicle and electrical components in water is prohibited.
Q: What is the most important thing I can do to maintain my battery?
A: Remember to charge your bike in a timely manner and do not leave it with an empty battery. Remember, if you don't use the battery for a long time, charge the battery every 2 months or the battery will starve to death because it has no power. No power. This will result in short trips or the display not coming on.
Q: Do you have a spare key for my e-bike?
A: Hi, we don't have a spare key, please keep your key safe in case you lose it.
Q: What is the range of my VARUN battery?
A: This depends on the situation, on factors such as the battery itself (capacity, condition, charging cycles); the landscape (even in the mountains); the weather (tailwind or headwind, cold/warm); the power support (low/high), etc. It is generally impossible to answer. Under laboratory conditions, each VARUN bike was driven over 100 kilometers during the test. It is recommended that you use the Pedal Assist mode, which improves range.
Q: From time to time, my display gives me errors, flashes, and occasionally goes out instead of coming on!
A: There may be poor battery contacts here. First clean the contacts on the battery, spray with WD 40 / Caramba or similar product and check that the battery is correctly placed in the supplied stand. If the battery is wobbling in the support, secure it. If the display goes out while driving, the contact between the battery and the control unit may be broken. It also makes sense to check the contacts on the control unit directly here.
Q: Can the handlebars of the M27-1, S26-1 and M24-1 be raised?
A: The height of the handlebars on these models is not adjustable and can only be adjusted with "handlebar risers" from specialized dealers. Since our bikes come in standard sizes, there are a variety of options here. Other handlebar models can be raised.
Q: I want to buy another bike!
A: Ask our sales people for a "loyalty discount" on another new bike or a cheap refurbished bike (1 year warranty). We are here to help, just send us an e-mail.
